Description

Technical Field

[0001] The invention relates to the technical field of outboard motor test benches, in particular to an outboard motor comprehensive performance test bench. Background Art

[0002] An outboard motor is a small engine installed on the outside of the hull, mainly used for the propulsion of small ships. Its main components are an engine and a propeller. The engine provides power to the propeller, which drives the propeller to rotate and generate thrust to push the ship forward. In order to ensure the safe operation of the ship, the reliability of the propeller needs to be tested by a dynamometer. In actual navigation, the propeller will be affected by various external forces, such as water impact, collision with debris, etc. Through testing, potential defects and weaknesses of the propeller can be discovered, and timely repairs or replacements can be made to avoid failures during navigation.

[0003] When using a dynamometer to test an outboard motor, the dynamometer is first installed on a test bench, and then the outboard motor to be tested is fixed to the test bench through an outboard motor hanging plate, so that the dynamometer and the output shaft of the outboard motor propeller are fixedly docked through a transition shaft and a transition shaft sleeve, and the outboard motor propeller is started to rotate to allow the dynamometer to test the performance of the outboard motor. Since the shaft center heights of the installed outboard motor propellers are different when testing outboard motors of different models, the staff is required to continuously adjust the position of the dynamometer according to the shaft center heights of the installed outboard motor propellers, which increases the difficulty of docking the dynamometer with the outboard motor propeller.

[0004] At the same time, the dynamometer and the outboard motor are not integrated. During the testing process, the outboard motor vibrates and the dynamometer is in a static state, which causes the connection between the dynamometer and the outboard motor to be offset. It is easy for the dynamometer to cause errors in the test results of the outboard motor, reducing the accuracy of the outboard motor performance test. In view of the shortcomings of the existing technology, we propose an outboard motor comprehensive performance test bench to solve the above problems. Summary of the invention

It should be noted that the horizontal trapezoidal driving block 101 and the vertical trapezoidal block 111 are respectively located directly above the X-axis reset driving plate 10 and the Y-axis reset driving plate 11, and the distance between the horizontal trapezoidal driving block 101 and the X-axis reset driving plate 10 is the same as the distance between the Y-axis reset driving plate 701 and the Y-axis reset driving plate 701. The heights between the plates 11 and the vertical trapezoidal blocks 111 are equal. When the driving cylinder 301 drives the dynamometer 5 and the outboard motor assembly 4 to move upward, the Y-axis reset driving plate 11 and the X-axis reset driving plate 10 are respectively contacted with the transverse trapezoidal driving block 101 and the vertical trapezoidal block 111, so that the transverse trapezoidal driving block 101 and the vertical trapezoidal block 111 are inserted between the Y-axis reset driving plate 11 and the X-axis reset driving plate 10 on both sides, respectively driving the Y-axis reset driving plate 11 and the X-axis reset driving plate 10 away from each other, so that the locking blocks 803 on both sides are away from each other, and the locking member 801 is no longer locked, thereby restoring the deformation of the driving spring 705, driving the two sets of correction plates to automatically reset, so as to perform correction operation on the next set of outboard motor assemblies 4 of different models.

[0032] For details, please refer to the attached Fig.14 The outer walls of both sides of the simulated water tank 2 are fixedly connected with fixed rods 103, a transverse trapezoidal driving block 101 is fixedly connected between the fixed rods 103 on both sides, a vertical trapezoidal block 111 is fixedly connected to the inner side of the fixed rods 103, and a positioning plate 102 is fixedly connected to the side wall of the transverse trapezoidal driving block 101. For details, refer to the attached Figure 7 , the outer peripheral wall of the connecting rod 304 is slidably sleeved with a first positioning piece 7033, and a connecting rod 7034 is fixedly connected between the first positioning pieces 7033 on both sides. It should be noted that the transverse trapezoidal driving block 101 and the Y-axis reset driving plate 11 are set to be longer, so that the correcting component 7 can always make the transverse trapezoidal driving block 101 and the vertical trapezoidal block 111 located directly above the Y-axis reset driving plate 11 and the X-axis reset driving plate 10 according to the position of the axial center height of propellers of different models. Under the action of the driving cylinder 301, the two sets of correcting plates are reset. The outer peripheral wall of the connecting rod 7034 is slidably sleeved with a second telescopic rod 7032, and the bottom of the second telescopic rod 7032 is fixedly connected to one end of the first telescopic rod 7031. The outer peripheral wall of the connecting rod 304 is fixedly sleeved with a second positioning piece 7035, and the first positioning piece 7033 contacts the second positioning piece 7035 to position the position of the correcting component 7 after movement.

[0033] Working principle: Before the outboard motor assembly 4 is inspected, the transition sleeve shaft 401 is fixedly connected to the propeller output shaft at the outboard motor assembly 4. At this time, the transition shaft 501 is away from the transition sleeve shaft 401. The outboard motor assembly 4 is fixedly installed on the outboard motor hanging plate 303. By starting the driving component 6, the driving component 6 drives the correction component 7 to move horizontally and vertically, and the transition sleeve shaft 401 is corrected within the angle formed by the X-axis correction plate 701 and the Y-axis correction plate 702. At this time, the outer wall of the transition sleeve shaft 401 is respectively fitted with the outer wall of the X-axis correction plate 701 and the Y-axis correction plate 702, and the position of the transition shaft 501 and the transition sleeve shaft 401 is corrected and positioned so that the transition shaft 501 and the transition sleeve shaft 401 are on the same horizontal line. Then the electric telescopic rod 502 works to drive the transition shaft 501 to be connected and fixed with the transition sleeve shaft 401. After the transition shaft 501 is connected and fixed to the transition sleeve shaft 401, the dynamometer 5 and the outboard motor assembly 4 are moved down together to the inside of the simulated water tank 2 by starting the driving cylinder 301, and the propeller of the outboard motor assembly 4 is rotated by starting the outboard motor assembly 4. The power of the engine of the outboard motor assembly 4 is tested by the dynamometer 5 to ensure the normal use of the outboard motor assembly 4. During the rotation test, the transition shaft 501 is driven to rotate by the transition sleeve shaft 401, so that the linkage component 9 can work, so that the push block 906 pushes the second driving rod 7021 to move horizontally, so that the Y-axis correcting plate 702 slides on the bottom of the X-axis correcting plate 701, and then the position of the Y-axis correcting plate 702 after movement is positioned by the locking component 8, so that the Y-axis correcting plate 702 does not contact the outer walls of the transition shaft 501 and the transition sleeve shaft 401, and at the same time, the linkage component 9 pushes the triangular block 7011 to move vertically, so that the X-axis correcting plate 701 can move upward, and the position of the X-axis correcting plate 701 after movement is positioned by the locking component 8, so that the X-axis correcting plate 701 does not contact the outer walls of the transition shaft 501 and the transition sleeve shaft 401, so that during the high-speed rotation detection, the two sets of correcting plates can be prevented from fitting against the outer walls of the transition shaft 501 and the transition sleeve shaft 401, causing damage to the outer walls of the transition shaft 501 and the transition sleeve shaft 401; After the detection, the dynamometer 5 and the outboard motor assembly 4 are moved upward as a whole by driving the cylinder 301 and are separated from the interior of the simulated water tank 2. During the upward movement, the X-axis reset drive plate 10 is brought into contact with the transverse trapezoidal drive block 101, and the Y-axis reset drive plate 11 is brought into contact with the vertical trapezoidal block 111. The transverse trapezoidal drive block 101 and the vertical trapezoidal block 111 are respectively inserted into the interior of the X-axis reset drive plate 10 and the Y-axis reset drive plate 11 on both sides, so that the X-axis reset drive plate 10 and the Y-axis reset drive plate 11 on both sides can be driven to separate respectively, so that the locking component 8 no longer locks the X-axis correction plate 701 and the Y-axis correction plate 702, so that the X-axis correction plate 701 and the Y-axis correction plate 702 can be automatically driven to perform a reset operation, so as to facilitate the correction detection of the next group of outboard motor assemblies 4; When driving the deflection correction component 7 to move horizontally and vertically, first start the driving motor 606 at the vertical frame 602 to drive the second transmission screw 604 to rotate, so that the driving member 605 drives the dynamometer 5 and the deflection correction component 7 to move slowly vertically, so that the bottom of the X-axis deflection correction plate 701 contacts the top of the transition sleeve shaft 401. After the contact, the driving motor 606 stops working, and then start the driving motor 606 at the horizontal frame 601 to drive the first transmission screw 603 to rotate, so that the driving member 605 drives the vertical frame 602 and the dynamometer The machine 5 and the correcting assembly 7 slowly move laterally, so that the Y-axis correcting plate 702 contacts the outer wall of the transition sleeve shaft 401. After the contact, the driving motor 606 stops working. During the movement of the correcting assembly 7, the transition shaft 501 at the dynamometer 5 moves along with it, so that the transition shaft 501 and the transition sleeve shaft 401 are in the same horizontal line. Then the electric telescopic rod 502 works, driving the transition shaft 501 to move to one side of the transition sleeve shaft 401, so as to realize the accurate docking of the transition sleeve shaft 401 and the transition shaft 501.
